TACHINIDAE OF ORIENTAL REGION 133 



male holotype (in BMNH, London) shows that it is a specimen of the Palaearctic 

 species G. capitata (De Geer), and no specimens have ever been found from India 

 or elsewhere in the Oriental Region that would suggest that oestroides truly occurs 

 there. 



The Oriental Goniini have the following characteristics in common. 



Eyes bare. Frons and facial region exceptionally wide, parafrontal very much wider than 

 interfrontal area and parafacial at least 1 -5 times as wide as third antennal segment (usually 

 more). Ocellar setae very strong and reclinate. Both sexes with strong outer vertical setae. 

 Occiput without black setulae behind the postocular row. Vibrissae inserted above the level 

 of the epistomal margin. Antennae long, conspicuously longer in £ than §; arista thickened 

 on at least two-thirds of its length and usually with the second segment very greatly elongate 

 (not in Spallanzania). Prosternum setulose, propleuron bare. Humeral callus with three 

 strong setae standing in line; two posthumeral setae; 1 + 3 ia setae; 3 + 4 dc setae; pra seta 

 very long and strong. Infrasquamal setulae absent. Barette completely bare. Scutellum 

 without apical setae but with two or more spiniform setae directed upwards just before the 

 apex. Mid tibia with two or more ad setae and with one or two submedian v setae. Cell 

 R b open; second costal sector bare ventrally; R t+S with a few setulae above and below on the 

 basal node, veins otherwise bare. Abdominal Ti + 2 excavate; intermediate abdominal 

 tergites without discal setae; abdomen rotund, T5 deep and apically compressed to a narrow 

 slit concealing the terminalia. 



The Goniini are parasites of Macrolepidoptera, principally of Noctuidae. All 

 recorded Oriental hosts are noctuids, especially the bolhvorms (Heliothis) and army- 

 worms (Spodoptera). An interesting recent host-record is that of an unidentified 

 Spallanzania species attacking Heliothis assitlta in northern India (Achan et al., 

 1968): a specimen from this rearing is in the BMNH collection and the identity 

 as Spallanzania sp. near hebes Fallen is here confirmed. 



Key to Oriental Genera of GONIINI 



1 Parafacials bare. Scutellum with two pairs of marginal setae (basals and subapicals, 



the laterals completely absent). Facial ridges setose on most of their height. 

 Three stpl setae (arranged 2 + 1) . . . GONIOPHTHALM US Villeneuve 



- Parafacials haired or setulose. Scutellum with three pairs of marginal setae (strong 



laterals present in addition to basals and subapicals). Facial ridges bare. Usually 



four stpl setae (if three then arranged 1 + 2). . . . . . . 2 



2 Facial ridges conspicuously convex, easily visible in profile on most of their height. 



Thorax with long soft yellow hair on the pleural regions. Genal, and at least 

 some of the parafacial, hairing pale yellow. $ with proclinate orbital setae. 

 Tegula reddish TURANOGONIA Rohdendorf 



- Facial ridges not noticeably convex, not or only slightly visible in profile. Thorax 



with normal entirely black hair. Genal and parafacial vestiture entirely black. ^ 

 without proclinate orbital setae. Tegula black or brownish black ... 3 



3 Second segment of the arista extremely elongate (several times longer than wide 



and subequal in length to the last section of the arista). Parafacials with vestiture 

 of very irregular size, the vestiture adjacent to the facial ridges very strong and 

 setiform (sometimes forming an almost regular row of setae). Basicosta usually 

 yellowish brown to dark brown, often not conspicuously paler than the tegula

- Second segment of the arista short (not more than twice as long as broad and very 



much shorter than the last section of the arista). Parafacials with vestiture of
